Adjusting The Handpiece
The handpiece knob and the body (barrel) are threaded
together, allowing the hose to be rotated to the position
the user prefers. The length of the handpiece can be
extended by unscrewing the knob and body even more.
NOTE: Extending the length may cause a slight loss of
power depending on the type of work being done.
With the locking ring slightly
loose, the handpiece body
and knob can be turned
independently. Position the
Quick Change holder with the
graver “point” down and rotate
the knob until the hose position
is the most comfortable. Once
the hose and graver are both
positioned comfortably, tighten
the locking ring.
How To Attach New
Hose
Loosen the locking ring and
remove the knob from the
handpiece. Remove the old
hose simply by cutting it off
close to the knob. With a
small punch, push the hose/
brass fitting back into the knob
body. Remove the brass fitting
(#004-422 Air Hose Retainer)
from the old hose. Feed the
new air hose through the hole
in the knob
(
FIG. 1
). Insert the brass
fitting into the end of the hose
making sure it is fully seated.
Moistening the fitting first may
help it slip into the hose easier.
Then apply a small amount of moisture or oil around the
outside end of the hose next to the brass fitting and pull
the hose back
(
FIG. 2
) into the knob until you see the tip of the brass
fitting protrude through the side of the knob. This must be
an air tight fit, so you will have to pull somewhat hard (a
few pounds, at least).
